PREFACE
Mathematics forms the essential foundation of electrical installation work. Without applying mathematical functions we would be unable to work out the size of a room which needs lighting or heating, the size and/or the number of the lights or heaters themselves, the number and/or the strength of the fixings required, or the size of the cables supplying them. We would be unable to accurately establish the rating of the fuse or circuit breaker needed to protect the circuits, or predict the necessary test results when testing the installation. Like it or not you will need to be able to carry out mathematics if you want to be an efficient and skilled electrician.




This book will show you how to perform the maths you will need to be a proficient electrician. It concentrates on the electronic calculator methods you would use in class and in the workplace. The book does not require you to have a deep understanding of how the mathematical calculations are performed; you are taken through each topic step by step, then you are given the opportunity yourself to carry out exercises at the end of each chapter.




Throughout the book useful references are made to Amendment 2:2004 BS 7671 Requirements for Electrical Regulations and the IEE On-Site Guide.

Volume 2 Electrical Installation Calculations originally written by A. J. Watkins and R. K. Parton has been the preferred book for many students looking to improve their mathematical understanding of the subject for many years. This edition has been newly updated not only to include modern methods, but also to cover all aspects of the new City and Guilds 2330 Certificate in Electrotechnical Technology.




This second volume includes advanced calculations, in particular those involving cable selection. As well as being invaluable to students studying for the City and Guilds 2330, it will also be of considerable use to those involved in electrical installation work, particularly if studying for the City and Guilds 2391 Inspection and Testing, 2400 Design and Verification and the 2381 exams.
Use of calculators




Throughout Books 1 and 2, the use of a calculator is encouraged. Your calculator is a tool, and like any tool practice is required to perfect its use. A scientific calculator will be required, and although they differ in the way the functions are carried out, the end result is the same. The examples are given using a Casio fx-83MS. The examples are given using a Casio fx-83MS. The figures printed on the button is the function performed when the button is pressed. To use the function in small letters above any button the shift button must be used.
